How much is a Guinea worth?

What is a Guinea?


The Guinea was originally produced in 1663 and was the largest denomination in British currency until
it was replaced by the Pound in 1816. The name ‘Guinea’ apparently refers to the fact that the gold used
for minting coins in the 17th Century was supplied by the Africa Company, who operated along the
Guinea Coast in West Africa.

It had a nominal face value of around 20 Shillings, the equivalent of a pound in today’s money, although
this value fluctuated as high as 30 Shillings. It was the first English gold coin to be produced by a machine.

Guineas vary in price, from a few hundred pounds to several thousand. Guinea coins are still worth a
considerable amount due to their gold content. A Guinea is a 22 carat gold coin that weighs 8.3g and,
as is the case with other gold bullion coins, its value is calculated by multiplying its gold content by the
current gold spot price.

Since British currency was decimalised on 15th February 1971, the Guinea has no longer been accepted
as legal tender. The term is still used in certain circles such as horse racing to describe values equivalent
to one pound and one shilling, or £1.05 in modern currency. As it is no longer classed as legal tender, the
Guinea differs from other British bullion coins such as Britannias and Sovereigns in that it is not exempt
from Capital Gains Tax.


Half Guinea coins

There are also several smaller Half Guinea coins that are also all 22 carat gold (91.6% gold purity). Their values are calculated in the same way as the full Guinea and other bullion coins.
